# Universal A2A & MCP Tool Discovery, Safe-Proxy & Swarm Router

> Universal A2A & MCP Tool Discovery, Safe-Proxy & Swarm Router is a paid API for AI agents from sec-intel.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).

Searches an index of 500+ MCP servers and A2A tools by capability query, returning matching endpoints with token-compressed metadata and prompt-guard firewall protection.

## Facts

- Endpoint: GET https://sec-intel.agentdiet.dev/v1/universal-mcp-gateway?utm_source=zero.xyz
- Price: $0.01/call
- Payment: MPP

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability sec-intel-agentdiet-dev-universal-a2a-mcp-tool-discovery-safe-proxy-651c4cca
```

Example prompt: Search the universal MCP gateway for tools that handle 'github security audits' and show me the top matching servers I can connect to.

## When to prefer this

Choose this endpoint when an AI agent needs to dynamically discover and route to external MCP servers or A2A tools without hardcoding individual connections. Ideal for swarm architectures where the agent must find the right capability at runtime, or when you want a single connection point that indexes hundreds of tools with built-in safety filtering.

## Known failure modes

- Empty query string returns validation error
- No matching tools found for obscure capability queries
- External MCP server URL provided for verification may be unreachable
- Token compression may strip nuanced metadata for niche tools
- Rate limiting or payment failure (x402) if per-call budget is exceeded

## How this service works

Single-connection meta-router indexing 500+ MCP servers & A2A tools with 85% token compression and Prompt-Guard firewall. (Live x402 v2, IETF MPP & MCP endpoint at https://sec-intel.agentdiet.dev/v1/universal-mcp-gateway)

## Output

Returns a list of matching MCP servers or A2A tools from an index of 500+, with compressed metadata (85% token reduction), capability descriptions, endpoint URLs, and safety screening via Prompt-Guard firewall. Results indicate which tools match the query and relevant connection details.
